探讨先天性巨结肠的内镜下特点,采用内镜检查诊断先天性巨结肠,并与 X线钡剂灌肠检查相对照。42例术前行内镜与 X 线钡剂灌肠检查,根据影像学特点用上述两种方法测量肠管长度,并与术中结果进行比较。结果:镜下特点,1.扩张段:一个视野不能表达一个肠腔横断面。2.移行段:漏斗状。3.狭窄段:呈“隧道征”。并发症有慢性结肠炎,结肠溃疡、息肉,肠虫症。结论:内镜检查也是诊断巨结肠的重要方法之一,且直视下可判断手术效果及术后并发症。 Explore the characteristics of endoscopic Hirschsprung’s disease, endoscopic diagnosis of Hirschsprung’s disease, and with X-ray barium enema check. Forty-two patients underwent endoscopic and X-ray barium enema preoperatively. The length of the intestine was measured by the above two methods according to the imaging features and compared with the intraoperative results. Results: Microscopic features, 1. Expansion of paragraph: a field of vision can not express a cross-section of the intestine. 2. Migration section: funnel-shaped. 3 narrow section: was “tunnel sign ”. Complications of chronic colitis, colon ulcers, polyps, intestinal worms. Conclusion: Endoscopy is one of the important methods to diagnose megacolon, and under direct vision can judge the effect of surgery and postoperative complications.
